Toe-clipping has been widely used for individual identification of amphibians and reptiles. It is costless and easy to apply and read. An animal's locomotor speed may affect its ability to acquire food, to avoid predation, and to achieve a high social status. Thus, it is of interest to determine whether toe-clipping affects the running speed of lizards. Wild caught Eastern Water Skinks (Eulamprus quoyii) were run in a race track in three consecutive sessions. In the first session, all animals were run with their toes intact. Half of the animals had their toes clipped between the first and second session, whereas the other half were toe-clipped between the second and the third session. Neither the average or maximum running speeds of lizards were affected by toe-clipping.
